Spray Foam Insulation Phoenix and ventilation reduce energy costs, improve home comfort, and increase the resale value of your house. While enhancing your home with new insulation may require an initial investment, energy savings and improved air quality will pay for the project in no time.
A well-ventilated attic prevents heat buildup in the summer and moisture accumulation during winter. This helps protect the roof deck, extend the service life of shingles and other roofing materials, and minimizes wood rot. In cold climates, proper attic ventilation is also critical to control ice damming and to vent moisture that moves through the ceiling air barrier from conditioned spaces, ductwork penetrations, or from non-airtight recessed lights.
The Connection Between Attic Ventilation and Insulation
An effective ventilation system is usually a combination of soffit and ridge vents, configured to allow for a steady flow of air. These systems work by passively leveraging the natural tendency of warmer air to rise and cool air to sink. These systems also incorporate baffles to block soffit vents from being blocked by insulation or ice, and they ensure that the full length of attic rafters is ventilated.
Insufficient attic ventilation not only raises energy bills but also jeopardizes the shingle warranty. Shingle manufacturers often include attic ventilation requirements in their warranties, and failure to meet those conditions can render the warranty void.
Moisture from a poorly ventilated attic can cause mold and mildew problems throughout the house, as well as corrosion of metal components such as nails, fasteners, and HVAC ducts. A musty odor in the rooms below the attic is another indicator of moisture problems.
